BED REGULATOR AND CHATTER FOR JIcs Application filed October 11, 1926. Serial No. 140,974.

This invention relates to a novel apparatus for separating strata of ore,,ore bearing material and waste material passing over an ore separating jig, and more particularly to a chatter, and bed regulator -for jigs.

The principal object of my invention is to provide novel means for separating from waste material and conducting away .by different channels clean ore and ore bearing chats in a more efficient manner than has been possible with the devices heretofore used. I

An important object of my invention is to provide a novel combination between the grate or bed of a pulsating jig and a separating devicewhereby an eddy is produced which tends to move the separated material more readily through the separating device.

A further object of my invention is to provide means whereby a constant bed of ore is maintained on the jig grate.

1n the accompanying drawings I have shown a preferred.lembodiment of my invention. In this showing,

deferring to Figures 1 and 2 of the ac companying drawings, reference numeral 10 indicates generally a conventional type of pulsating jig [consisting of a plurality of compartn'ients each of which is provided with ;a hutch 11 having inclined bottom plates or baflles 12, a reciprocating plunger 13, and a plunger rod 14: suitably connected to anveccentric 15 mounted on the shaft 16, whereby the plunger 13 is caused to-reciprocute upon the rotation of the shaft 16in an obyious manner. The shaft 16 ;is suitably journaled as at 17 on stationary ,portions of the 10. At one sidelof the hutch 11 near the upper portion thereof provided the usualgrate 18 (Figure 2) over which. the crushed material from an, ore crusher is adaptedto pass in the usual manner. The

is a section on line '77 of Figgrate 18 is suitably mounted on supports 19. btrata separating devices generally indicated by the numeral 20 are mounted on the grate in each compartment of the jig and are obliquely disposed with relation thereto for a purpose hereinafter to be described.

The crushed material from the crushing mill is adapted to pass over the grates of the in a direction indicated by the arrows in Figure 1 and water is caused to pulsate through the jig bed or grate 18 in a known manner to cause the crushed material'to form strata of clean ore, chats or ore bearing material, and gangue or waste material by virtue of the difference in specific gravity of the various materials. As is convene tional, each successive compartment of the jig is at a lower level than the next preceding compartment.

It has been the practice to provide means for separating the strata of materials passing over the gig grate but the devices which have been employed up to the present time have had .the disadvantage that a considerable amount-of the chats would be pulled or carried with the ore and an excessive amount of the gangue or waste material would be carried off with the chats; To overcome this serious disadvantage I have provided a novel construction which will separate the strata in a more satisfactory manner than has heretofore been possible. I have found that my chatter will fpull less waste by 75% than any of the chatters with which I am familiar. Y

My chatter or separating device 20 com- -p,rises spaced horizontally disposed plates 21 and 2 which form an opening therebetween. The plates 21 and 22 are pro yided with sharp forward edges. The open ing 23 between the plates 21 and coinmunicates with a channel or chat runway 26: the bottom of which is open to the action of the pulsating water through the grate substantially throughout the length thereof.

I Tl'lEllOl'lZODtZll plate 21 is [secured ;;to or forms a part of the substz intially vertical supporting plate wh ch also forms one side of the chat runway Suitably secured below the plate 2-2 andrearwardly of the front edge thereof is a. substantially vertical plate 26 provided with a plurality of openings 27 ;in the face thereof. The openingsQT communicate with a channel or ,ore runway 28 one side of which is formed by the substantially vertical plate 29 which supports the horizontal plate and the bottom of which is closed substantially throughout its length but is provided with an opening 30 near its forward end. The plate 26 is provided with a rearwardly formed baflle 31 arranged below the opening 27 and extending over the opening 30 in the bottom of the runway The battle 51 serves the purpose of deflecting the pulsating water coming through the opening .30 rearwardly to prevent the water from moving over the opening 27 near the forward end of the chatter and hindering the ready passage of the ore through the opening ".27. The runways 2i; and Q8 communicate at one end thereot with suitable hoppers 232 and $32} which are provided with outlet openings ill and 55 which communicate with suitable openings 36 in the sides of the The openings 34- and 35 are provided with control gates 37 to regulate the rate of flow of the separated materials.

In the operation ot the device the crushed 1 material passing over the grate lorms strata of ore. chat-i and gangue by virtue of the pulsations of water through the jig grate. These materials in strata are encountered in their movement across the bed of the by my improved separating device. The horizontal plate 21 is designed to enter at the line of dcn'iarkat-ion between the waste material and the ore bearing chats. The waste material passes over the plate 21 and the chats enter the opening 23 between the plates 21 and 92. the latter being designed to enter the stratified materials at the line of demarkation between the chats and the ore. The chats passing into the opening 23 enter the chat runway 24 and pass therealong to the hopper 32 and through the opening and one of the openings 36 from which point they are conducted away for further working over to extract the ore which they contain. A portion of the stratun'i of ore is caused to enterthrough the openings 27 into the runway in along which it passes into the hopper ill and out of the outlet opening 35 and one of the openings St in the side wall of the hrcause of the inclined relation of the separating device to the moving current of crushed materials an eddy is set up which moves in a direction from the 'torward end of the device towa d the hopper end with the result that the chats and ore passing into their respective runways are caused to move more readily along the runways to the hoppers. Since the chats do not move readily over a plane surface, the bottom of the chat runway is open tliroughout its length to the pulsations of water throughthe grate to assist the movement of the chats along the runway 24. However. the clean ore moves very readily over a surface and, hence the bottom of the ore run ay 28 is closed throughout the greater portion of its length to prevent any substantial amount of the ore passing through the grate in into the bottom of the hutch 11. Only a small opening is provided in the bottom of the runway 28 to admit the. pulsating water into the runway to assist in movin; the ore therealong.

In order to provide a constant bed of ore on the grate so that the ore n'ioving along the will more readily pass thercover the openings 27 are spaced from the bottom of the vertical plate 26 so that the lower portion of the plate 26 forms a. dam to prevent the lower portion of the stratum of ore from moving along.

From the foregoing description it, will be apparent that l have provided an extremely simple device for se iarating the various strata oi crushed material passing over the bed of a This device is susceptible of ready application to the existing types of in operation and this feature is also an important. object of my invention.
